Some really useful information in this thread...so bump (could also be placed in the food thread I think)...
For those who may be interested in finding real flank steak... It comes specifically from the cut called 'dünner Lempen' in German. I ordered some today from
a very fine Metzgerei in Oerlikon for 24 CHF/kg. It will take about 5 days once ordered... If you plan to order from your local butcher, make sure you are talking about the same piece of meat...they may try and push off some 'seidfleisch' to you, which comes from the belly region and does not work the same as flank steak...
